Knoxville, 'lf'enn. 7 Application Aprir s, 1935,5ma1sd'ii50a 1 Claim. (c1. so- 1 v l This invention relates tosafety razors, animportant object of the invention being to provide a safety razor including a blade having four cutting edges, the construction of the razor being such that when in operation, two cutting edges are exposed, the remaining cutting edges being guarded.

Another important object of the invention is to provide a razor of this character so constructed that the handle will be substantially waterproof eliminating any possibility of water entering the handle to cause rust or corrosion.

A further object of the invention is the provision of a safety razor which may be thoroughly cleaned and adjusted without the necessity of dismantling the razor.

Still another object of the invention is to provide yieldable means for gripping and cushioning the blade, whereby the blade may be adjusted so that the user may shave close by merely tightening the handle. A still further object of the invention is to provide means for holding the blade against rotary movement on the shank of the razor, when the sections of the razor have been operated to facilitate cleaning of the razor.

In the drawing:

Figure 1 is a longitudinal sectional view through a safety razor constructed in accordance with the invention.

Figure 2 is a sectional view through the razor in its extended position for cleaning.

Figure 3 is an elevational view of the body portion of the razor.

Figure 4 is a sectional view taken on line 4-4 of Figure 2.

Figure 5 is a sectional view illustrating the means for securing the rubber cover to the guard member of the razor.

Figure 6 is a fragmental sectional view illus- 40 trating a modified form of rubber securing means.

Referring to the drawing in detail, the reference character 5 designates the shank or stem of the razor, the shank or stem being provided with threads 6 disposed at the outer end thereof, whereby, the shank or stem may be secured to the body portion 1 of the razor, the threaded end being positioned in a threaded opening of the body portion.

Formed on the shank or stem 5, and arranged 6 in spaced relation with the outer end of the shank, are ribs 8 which are spaced apart and disposed longitudinally of the shank. An annular flange indicated by the reference character 9 is formed integral with the shank or stem 5 at the 55 inner ends of the ribs 8, providing a support for the razor blade Ht, when the sections of the razor are loosened. andLSeparate-d to facilitate cleaning of thetrazorz. Thusiit willibe'. seen: that due to: this construction, it .is. unnecessary to dismantle the razor for cleaning purposes. 5

The handle of the razor is indicated by the reference character H and as shown, the handle is hollow and formed with an opening through which the reduced end l2 of the shank extends, the reduced portion I2 being headed so that the 10 handle is secured to the shank or stem 5.

Positioned within the handle and surrounding the shank or stem 5 of the razor, is a tubular member l3 that has a guard plate I4 formed at the inner end thereof, the guard plate being pro- 5 vided with the usual guard edges I5.

As clearly shown by the drawing, the inner surface of the body portion or plate I is covered by the strip of rubber material l6, Which is positioned by moulding the rubber to closely fit the 20 inner surface of the body portion 1.

The surface of the guard member l4, adjacent to the plate In, is also provided with a rubber cover I8, which is also held in position on the guard plate 14, by means of the clips 19, which 25 are embedded in the rubber material, and pass through openings in the guard plate, where they are bent over to engage the guard plate. It will of course be understood that the strip of rubber material which is reinforced by metallic strip I! may be secured to the member I by means of screws l9 which pass through the rubber material and strips H and are fitted in threaded openings of the member 1 as shown at Figure 6.

External threads 20 are formed on the tubular member l3 and are adapted to cooperate with the internal threads formed on the sleeve 2|, whereby the tubular member l3 may be secured in its active position, when the razor is adjusted for use.

One end of the sleeve 2| is reduced as at 22 and fits within a recess formed in the inner end of the handle ll.

As clearly shown by Figure 1 of the drawing, the tubular member I3 is formed with an inner tapered shoulder 23 adapted to receive the annular flange 9 formed on the shank or stem 5 of the razor preventing the shank or stem 5 from sliding through the tubular member l3, when the razor is adjusted for replacing the razor blade.

It will of course be understood that the razor blade, which is shown more particularly by Figure 4 of the drawing, is formed with openings 24, which openings receive the studs 25 extending from the guard plate l4, whereby the blade is held against rotary movement with respect to the guard plate l4. In order that the blade may be properly positioned, the openings 24 are numbered, and it will be seen that due to this construction, the user of the razor may know at all times, the edges which have been used in shaving, and the edges which have not been used thus facilitating the positioning of the blade with respect to the guard plate.

The blade is also formed with a central open-e ing through which the shank or stem extends, the central opening of the blade being formed with notches 26 that accommodate the ribs 8, preventing rotary movement of the blade with respect to the shank or stem 5, when the body portion 1 and guard plate l4 have been moved to facilitate the cleaning of the razor, without the necessity of dismantling the razor, to accomplish the cleaning result.

It might be further stated that because of the rubber members l6 and I8, the blade I0 is securely gripped, and by merely rotating the sleeve 2|, pressure on the blade 10 may be increased or decreased, to the end that the blade may be regulated so that the user may get various types of shaves, and at the same time the rubber members will protect the various elements of the razor from moisture insuring against the formation of rust or corrosion.

Having thus described the invention, what is claimed is:

A safety razor comprising a shank, an enlargement on the shank, a body portion secured to one end of the shank, a tubular member positioned on the shank and having a shoulder with which the enlargement engages restricting movement of the shank through the tubular member, a guard plate on one end of the tubular member, spaced longitudinal ribs on the shank, a blade having a central opening through which the shank extends, said blade having notches adjacent to the central opening and adapted to accommodate the ribs preventing rotary movement of the blade with respect to the shank, and means for moving the guard plate into clamping relation with the body portion clamping the blade therebetween.
